BOBBIN FOR SYNCHRONOUS MOTOR OF CLOCK

摘要

PROBLEM TO BE SOLVED: To provide a bobbin for synchronous motor of a clock for reducing costs and facilitating the control of the bobbin while retaining the size of a stator. SOLUTION: In the bobbin 2 for synchronous motor of a clock with a core part 2d that is provided with a through hole 2c where one arm 3b of a stator 3 being formed in a flat-plate shape and in nearly a U shape is inserted and where a coil is wound at an outer-periphery part and side walls 2a and 2a being provided at both the ends of the core part 2d, a cut-out 2b for penetrating the other arm 3c of the stator 3 is provided at the outer-periphery part of the side walls 2a and 2a, thus coping with the stator where the interval between both the arms differs with a single bobbin.
